PIPE-ORGAN STRUCTURE.

Application filed December 21, 1922.

To @ZZ fin/'tom may concern.'

Be it known that I, Lnvi M, limitan, residing at Pittsburgh, in the county oi' llegheny and State of Pennsylvania, a citizen ot the United States, have invented or discovered certain new and useful Improvements in Pipe-Organ Structures, ot which improvements the following is a specification.

lvly invention relates to improvements in pipe-organ structure and consists in means tor arranging combinations of stops, which combinations, having been set up beterehand, maybe brought alternately and rep `a'itedly into service, as the player may desire.

ln the accompanying d lawings F ig. is a view in plan and Fig. l] a. view in side elevation of apparatus embodying my present invention; Fig. Ill is a view in vertical section ot a portion of this apparatus, the plane ot section being indicated by the line lll-lll, Fig. l; Fig. IV is drawn to larger scale and illustrates in side elevation and in section a. detail shown in Fig. lll; F V is a view in vertical section, on the plane indicated at V--V, Fig. l; Fig. Vl is a view in vertical section, on a plane at right angles to that ot Fig. V, on the plane indicated at Vl-Vl, Fig. V. It will be perceived 'that Ill and Vl together' afford a view in longitudinal section ot the whole, though not in a single plane. ot section. Figs. VH, Vlll, 1X, and X are views, Fig. VH in horizontal section, Figs. VIH, IX, and X in vertical section, ot a certain switch which terms an essential part ot the invention. The planes ol section ot Figs. VH, Fill, 1X, and X are indicated by correspondingly numbered section lines, each on another iigure ot' this group, and will readily be understood. Fig. Xl is a diagrammatic scheine ot the electric wiring of the whole.

rlhe apparatus as I have here illustrated it, is in some sense. a model; it does not include the whole system of stops ot a pipe organ, but only three. I have so far reduced the number ot stops, in order to keep the showing simple. rl`his showing l eing clearly coinprehended, it will be manifest that to 00 apply the i vention to a complete system stops, however large that system may i., is

a mere matter ot duplication of parts.

show here three stops (or, to speak precis( three stop controlling levers) and two coinhinations,-that is to means tor setsay,

Serial ITo. 668,365.

ting up beforehand two arrangements ot these three stops, which arrangements being once set up, may alternately be brought into servire, as the player may desire. It will further be perceived that an increase in the number ot combinations, beyond what is here shown, and to any desired extent, is a mere mattei' ot duplication.

',lhe apparatus is electrical; mechanical parts are swung by electro-magnets, energized from a suitable source, and switched in and ont ot service in proper coordination.

Doininating the whole is a switch adapted to be swung from one to another of two alternate positions, When in one position the combinations may be set up. A'tter the combinations are set up, this switch may be shifted to its alternate position; and 'then one or anotl er ot the. already set-up conibinations may be made eifectn'e, as desired.

lfteterring to Figs. l and lfl, A is the tablet board ot' the console ot an organ; S are stopcontrolling levers; (il are combination buttons, and W are switch buttons. lt is to be understood, .first ol all, that the stop levers bl may be individually swung and stops operated in usual manner. My invention does not disturb that condition oftl things. rEhe organ may, accordingly, be used, without resort to my invention, the stops then beingl individually operated. My invention cornes into play and becomes valuable, when ,it comes to bringing into service all at once and through the pressing ot a single button a particular prcarrangod combination ot stops.

The switch which has already been referred to is lully illustrated in Figs. VlI-S, and will presently be described, Suilice it here to ren'iarlz that by pressing altemately one and the other of buttons lll, this switch may be thrown from one to the other otl its two operative positions. Let it be supposed that it has been thrown to the position preparatory to the setting-up ot stop combinations, the position which I shall hereafter designate as the setting-up position. lllhen the switch has been swung to this position, and when in sequence thereatter one or more ot stop levers S in desired combination have been shifted, either one ot' buttons C may be pressed; and thereafter, the switch having meanwhile been swung to its alternate position, wnich hereafter l shall Chiu-Miglia@ as playing position, whenever f of swinging.

this same button C is pressed, stop levers S will be shifted in this particular combination.

Referring particularly to Figs. I, III, and IV, a series of bars 1 will be remarked, mounted in suitable ways and adapted to be shifted longitudinally. Each bar carries a series of pivotally mounted contact pieces 2. One such bar is provided for each stop lever, and, accordingly, as I here show three stop levers S and no more, three bars 1 are present. Each bar carries a contact piece for each combination button, and since for present purposes I show two combination buttons C, each bar 1 here carries two contact pieces 2.

The bars 1 are arranged side by side in parallelism. At one end, the right-hand end, as seen in Figs. I and III, each barlis provided with a push rod 3 pivoted to 1t. These push rods are formed of soft iron and are subject each to the in'liuence of one of the three eleetromagnets 4, of which further mention will presently be made. At opposite ends of the series of bars 1 with their push rods 3 are arranged transverse rods 5 and 6 mounted to be shifted in the general plane in which the bars extend and in` a die rection longitudinally of the bars. A spring 7 engaging rod 5 tends always to hold the bars at one end (the right-hand end) of their range of longitudinal sliding.' A spring 7a engaging rod 6 tends always to hold it at the right-hand limit of its range An electro-magnet 8 when energized drives actuating rod 6 to the left against the tension of spring 7a and, engaging one or more of push rods 3, carries the corresponding bars 1 to the left against the tension of spring 7. If o-ne or more of magnets 4 be energized before the energizing of magnet 8, the corresponding push rods 3 will be drawn upward, out of the pathway of rod 6, and consequently when magnet 8 is energized and rod 6 shifted, the bars 1 whose push rods 3 have so been drawn aside will not be carried from right to left, as otherwise they would be.

Extending transversely beneath bars 1 are rods 9 mounted to be shifted transversely of their extent, that is to say toward and from the contact pieces, presently to be described, carried by bars 1. The rods 9 correspond in number to combination buttons C (and to sets of contact pieces 2), one for each button. The desired movement may conveniently be achieved by forming them as bends in rotatably mounted lengths of wire, after the manner clearly shown in Figs. I and III. Each of these lengths of wire is prolonged at one end to form a crank arm 10, and each crank arm 10 is linked to contact-shifting bar 40, and each bar t() is linked in turn to a soft iron push rod 11. The bars 40 lie side by side and in parallelism with the bars 1, and like the bars 1 are shiftable longitudinally, from right to left, as seen in Fig. I. The push rods 11 (two in number, because no more than two combination buttons C are shown) extend adjacent to and in approximate parallelism with and in approximately co-mmon plane with push rods 3 already described. Associated with each push rod 11 is an electromagnet 12. It has been explained, con cerning push rods 3, that when any of the magnets 4 is energized the corresponding push rod is drawn aside, out of the pathway of the swinging transverse rod 6. It is to be remarked concerning push rods 11 that, while they extend approximately in common plane with push rods 3, they lie normally out of the pathway of the swinging rod 6, and that when magnets 12 or any of them are energized the corresponding push rods 11 will be drawn into the pathway of swinging rod 6.

The push rods 3 and 11 are alike in this, that normally they rest by gravity in their lower position, that they are raised by the magnets 4 and 12, and that when a magnet is deenergized the corresponding rod swings by gravity to its initial position.

The transverse rod 5, swinging, carries bars 1 from left to right (Fig. III), and carries with the bars the push rods 3; the swinging' of rod 5 has no effect, to shift rods 9 nor to return bars 40 from left to rigl'it.

IVhen the switch is in playing position any one of the stop levers S may be independently swung, but the independent swinging of the stop lever under the conditions indicated will have no effect upon the electrically controlled apparatus which I here am describing.

lVhen the switch is in setting-up position, however, the shifting of a stop lever will effect the energizing of a magnet el. There are as many bars 1 as there are stops, and as many magnets l as there are stops; each magnet 4 is, under the conditions indicated, under control of one of the stop levers. Accordingly, when the switch stands in setting-up position, the shifting of a stop lever energizing the corresponding magnet, raises the corresponding push rod 3 out of the path of swing of transverse rod 6.

then the switch is in setting-up position, the pressing of either combination button C euergizes simultaneously one of the electromagnets 12 and also an electron'iagnet 30. The energizing of an electromagnet 12 raises the corresponding push rod 11 into the path of swingof transverse rod 6 g the energizing of electroniaguet 30 swings a spring-restrained rod 31 composed wholly or superficially of soft iron (in fact it is made of iron surfaced phosphor bronze) and closes an electric circuit which circuit, being closed, energizes a second electromagnet 13. lVhen Cfr electromagnet 13 is energized it raises against spring tension (or gravity) its armature 14, and in so doing closes another circuit. This circuit, being closed, energizes electroniagnet 8. rl`hereupon the armature 15 of magnet 8 is attracted and drawn, against the resistance of springs 7 and 7 with the result that transverse rod G is swung. By the swinging of rod 6 those bars 1 are shitted from right to left (Figs. l, IH) whose push rods 3 have not been drawn aside by electromagnets 4, and those bars 40 are shifted whose push rods 11 have been drawn aside by magnets 12. The shitting of a bar 40 effects the swinging ofl the corresponding rod 9.

The reason for the step-up or relay of energizing current through th-e successive magnets 30, 18, and 8, is to delay the swinging of transverse rod 6 until the push rods 3 and 11 shall surely have been swung selectively and come to position desired before rod 6 advances.

Each bar 1 carries as many contact pieces 2 as there are combination buttons C. Each line ot contact pieces 2 borne by the plurality of bars 1 is arranged adjacent the path of swing of one ot the transverse rods 9. The swinging of either rod 9 will effect the swing from inactive to active position of the corresponding contact pieces 2 upon so many of bars 1 as have not been driven from right to left by the swinging of rod 6,-those bars 1 whose push rods 3 have by the energizing of their magnets 4 been drawn aside 'from the path of rod 6.

Fig. XI shows all the Contact pieces 2 but one in inoperative position; and uppermost on the left, as there. shown, is in operative position. Fig lV shows the contact piece in detail, and indicates how it is pivoted to bar 1. lhe contact piece may be provided with a boss 211, and the bar may be provided with suitably placed recesses or pert'orations 1, to the end that (the body ot the contact piece being itself somewhat resilient), the contact piece will be held with suflicient security first in one and then in the other of its alternate, operative and inoperative positions. The swinging bar 9 engages the properly disposed surface 2b, to effect turning ot' the contact piece from inoperative to operative position.

The sequence of movements in the setting up ope-ration is this: (1) The. switch (presently to be described) is brought to settingup position; (2) such ones or stop levers S as are to be brought into combination are swung. rThereupon the corresponding eletromagnets 4 are energized and the push rods 3 of the corresponding bars 1 are raised out oit the path of rod 6. @ne of the combination buttons C then is pressed. The corresponding electromagnet l2 is energized, and the corresponding push rod 11 is drawn into the path ot rod 6. lilith a short and suicient delay, but by this same pressing ot' button C, the sequence of electroniagnets SO, 13, and 8 is energized, and transverse rod 6 is swung. The swinging ot rod G eli'ects the shifting out oi' the of so many of bars 1 as are not to ser ve in setting up the particular combination, and also the swinging of the appropriate rod '.lhc swinging ot this rod 9 ellects the shitting ot the corresponding contact pieces 2 upon those bars 1 which have remained stationary and have there- :tore become participants in establishing the particular combination.

It is the shifting selectively of certain ot the aligned contact pieces 2 on the series oi? bars 1 which establishes the combination. s shown in the orawings it is the righthand line of Contact pieces 2, on bars 1, Fig. l which is coordinated with the upper combination button C, and the left-hand line which is coordinated with the lower button.

)Viren a combination in one row has been set up in the manner described, a new coinbination ot stop levers may be swung and then the other button C pressed, and this second combination by duplicate instrumentalities will then be imposed on the second row ot contact pieces 2.

ll`he keys have now been fashioned (so to speak) by which either combination may be unlocked (that is, brought into operation) at will.

jrs l have said, the number of rows ot contact pieces 2, the number ot combination buttons C, and the number oit' sets ot interconnected operating instrumentalities may be increased indelinitely.

lt may be noted in passing that when, while the switch remains in setting-up position, the stop levers previously swung are swung back to normal (whereby the corresponding electromagnets 4 are deenergizcd), the subsequent pressing again ot a combination button previously pressed (effecting as it does the simultaneous swinging ot bar (i and ot the proper one of loops 9) will et- Ylfect the swinging baclr to inoperative position ot' Contact pieces 2 previously swung to operative position in that particular combination. rlhis is ettected by engagement of loop 9 with properly disposed surfaces 2C or' the contact pieces oit the receding bars 1.

Having now explained how combinations re set up by a selective swinging ol contact pieces 2 upon bars 1, it remains to explain how, when the switch has been shifted to playing position, the pressing ot either combination button C will el't'ect the swinging ot' stop levers S, in the previously set up combination.

Adjacent and extending transversely above bars 1 are swinging rods 16, one 'for each set ot' contact pieces 2,-one for each combination button C. Electromagnets 17 are provided, one for each combination button Each electromagnet 17 has a sott iron spring-backed (or weighted) armature, which alternately rises and Jr'alis as the electroniagnet is energized and deenergized, and in rising and falling the armature etlects the swinging ot the corresponding ro-d 16. Normally the rods 16 extend in positions remote from contact pieces 2; but when, on the pressing oit either combination button C (the switch standing in playing position), the corresponding electromagnet 17 is energized, the corresponding rod 16 will be swung, and electric circuit will be closed through so many oftl contact pieces 2 as have previously been shifted (atter the manner already described) trom inoperative to opy 'ative position.

For each stop lever S is provided a shift rod 18 (Figs. V and VT). These shiit rods are formed olf sott iron. They extend sub stantially vertiailly downward and terminate with their lower ends in horizontal alignment. These lower ends are turned or hooked as indicated at 18. Opposite the 'tree end ot each rod 18 is arranged an electromagnet 22 adapted when energized to draw its particular rod 18 against gravity (augmented iit need be by spring resistance) into the pathway in which a transverse rod presently to be described swings. The contacts made by the swinging of one of rods 1G will close circuits which energize such ones of electromagnets Q2 as correspond to the operative cont-act pieces 2, and, accordingly, certain ot rods 18 will be swung to accomplish the end indicated.

Vhen (the switch being in playing position) one ot the combination buttons C is pressed, not only will one ot the electromagnets 17 be energized. (with the ensuing operations already described); electromagnet 80, already described as serving in the settingup operation, will also and siniultaneously be energized. The magnet 8() being energized will draw rod 81 to itselic as before, and as before will close a circuit; but the circuit now closed will, in consequence of the shitting ot the switch, no longer energize eleetromagnet 18, but instead it will energize another electromagnet 28, and this other electreniagnet, by drawing to itself a spring-resisting (or gravity resisting) sott iron armature, will close another circuit and energize another electromagnet Q1. Precise ly as before, and through two step-up or relay actions electromagnet 21 will be energized by the pressing of either combination button C, but only at a substantial and sutticient interval atter the energizing o't one of the electromagnets 17, and also (and this too is important) at a suthcient interval after the energizing et so many ot electromagnets 22 as the particular combination requires. There is one step-up trom pressing button C to energizing electromagnets 22; there are two steps-up, from pressing button C to energizing electromagnet 21. The ditl'erence of one step affords the desired time interval for push rods 18 to come to place before the transverse rod swings to drive them.

The transverse rod 19, repeatedly alluded to above, swings in response to the energizing ot magnet 21 against the tension o't a spring 9.0 ,in a vertical path upward and in so doing engages and drives upward so n'iany ot push rods 18 as have previously been drawn by their clcctroinagnets 22 into the pathway o'tl rod 19. T his driving oi rods 18 upward swings the stop levers with which they severally are connected.

Simultaneously with the upward swing ot rod 19, the energizing of magnet 21 effects also the downward swing (against the same spring tension) ot a second rod 32. This rod 82, so swinging' downward, engages the hooked ends 18L or so many ot rods 18 as may then stand unresponsive to magnets Q2 but still in elevated position, and draws them downward, and swings the stop levers with which they are connected to inactive position. Thus the simultaneous swinging ot rods 19 and 82, one upward the other downward, insures the desired setting ot' the stops. Tncidentally the rod 82 may have a wing-like extension 8f to ensure the continued abutment ot the rising rod 19 against the ends ot rods 18. The rods 19 and 82 swing under tension of spring Q0 when magnet Q1 is deenergized to allow push rods 18 to swing to inactive position. A bellows 88 cushions the thrust ot the armature ot magnet Q1.

lr'iaguet il is deenergized immediately after action, on the release of the previously pressed button C. The stop-levers remain in the positions to which they have been brought, and the combination may then be modified by the player, by swinging the stop levers S individually, as he may desire.

)Vithout 'further elaboration, it will now be understood that, the desired combinations having been set up, by imposing on the rows ot contact pieces 2 particular arrangements, and the switch having been shifted from setting-up to playing position, with. the pressing ol a button C stop levers S will be swung in the predetermined combination, one button C after another may be pressed and the several predetermined combinations made el.- tective', and the same combination may be made etlective again and again, whenever the particular button which controls that combination is pressed.

Tffhen previously set-up combinations are to be destroyed, all that need be done is to shitt the switch to setting-up position and, all the stop levers being in inactive position,

llt)

to press the combination buttons C. The rods 9 then will swing and, all the bars 1 being driven back, all the previously swung Contact pieces 2 will by engagement with rods 9 be returned from op .fative to inoperative positions.

In summary of electromagnet energizing, magnets 1 are energized only when the switch stands in setting-up position, and are energized by the swinging of stop levers S; magnets 12 are energized only when the switch stands in setting-up position and are energized by the pressing of the combination button C; magnets 17 are energized only when the switch stands in playing position, and are energized only by pressing combination buttons C; and magnet 30 is energized by the pressing of either button C, whether the switch stand in setting-up or in playing position. It the switch stands in setting-up position, energizing of magnet 30 effects sequent energizing of magnet 13, and through it of magnet 8; if the switch stands in pla-ying position, energizing ot magnet 30 effects s-equent energizing ot magnet 28, and through it of magnet 21. It the switch stands in playing position, energizing ot one of magnets 17 effects the sequent selective energizing oit' magnets 22.

Referring to Figs. VII-X the switch structure will readily be understood in principle. The switch includes a rotary block 24, and operative connections, whereby the pressing of lirst one and then the other cic buttons IV will bring it to one or the other of its alternate positions. @ne or' these positions is that previously characterized the setting-up position; the other, playing position.

The block 24- is equipped with opposite series of contact pins 25. `When in one ot the two alternate positions, one series of pins closes circuit through a series ot leads, 26-27; when in the opposite position the other series of pins closes-circuit through another set of leads, 28-29.

In the diagrammatic showing, XI, a source of electric energy is indicate-d at 8l.

This may be understood to be a generator' of, say, 10 amperes at 1G volts. In this tigure leads 35, 36 are shown; and these, it will be understood are leat s through which the actual shitting of stops is edected-the stops inl the organ, distinguished trom the stop levers. According as the stop levers S are depressed the. electric circuit is closed through lead 35 and one of leads 36, to actually accomplish stop shitting in the organ.

In Fig. XI the switch is shown to be in setting-up position and all the other manually controlled contactsopen. It now one of stop levers S be depressed, contact will be made at a, and an energizing current, completed through the switch, will i'low through a magnet 4. One of push rods 3 will then be raised, out ot the path of swing ot transverse rod 6. lVhen thereafter a combination button C is pressed, contact will be made at and one ont magnets 12 and magnet 3() will be energized, circuit being completed through the switch. The energizing ot a magnet 12 will cause a push rod 11 to be drawn into the path of swing of transverse rod 6 the energizing of magnet 30 will cause armature 31 to be drawn to it and contact will be made at c. The closing or contact c will ei'liect energizing (through the switch) of magnet 13. lVhen magnet 18 is energized, it will draw its armature to itself and make contact at (l. When contact (l is closed, magnet 8 will be energized and bar 6 swung. rlhe swinging of bar 6 will by the instrumentalities described and under the conditions already brought about elliect'the desired selective swinging ot' contact pieces 2.

After these operations have been performed the switch may be swung to playing position. Then, it one of the combination l-:eys C be pressed, one of magnets 17 will be energized, the current being completed through the switch, and magnet 30 will simumtaneously be energized again. The energizing of a magnet 17 will effect the swinging of a. transverse rod 16 and a consequent contact or contacts with contact pieces 2, previously arranged. The making ot contact between a rod 16 and a contact piece 2 will close, through the switch, a circuit through one ot magnets 22, energizing it; thereby one of rods 18 will be swung into the pathway of swinging rod 19. The energizing of magnet 30, closing again contact at c, will now cause an energizing current (completed through the switch) to iiow through magnet 23; this will effect a making ot contact at e; and thereuponan energizing current will flow through magnet 21. rIhis will eiiect the swing of rod 19, upward thrust of rod 18 and depr-ession or' stop lever S, setting up the desired flow of cnrrent through lead 35 and the corresponding lead 36.

I have shown stop levers, and have shown swinging members S which are properly so termed. Manifestly, it is a mere mattei' of mechanical adaptation to apply my invention to an organ structure -in which the stops are operated by draw knobs instead ot levers. In the ensuing claims I shall use the generic term stop member, to include such alternate devices.

rlhe advantages of the structure which now I have described are, first, simplicity, and economy of space; second, while the rods 1S and their immediately associated parts, and the electromagnet 30 with its armature are mounted on the tablet boa-rd, the setting-np bars 1 with their immediately associated parts and the remainder ot the orllO gan operating apparatus as well may be located where one will, quite independently of the position of the console. The console itself, therefore, may be made small, and will accommodate itself more easily to extraneous conditions. Third, the apparatus which I have shown and described may be energized from the electric generator provided to operate the organ. And, finally, in connection with the advantages enumerated, a combination once set up may be brought into service again and again; the service of the apparatus is not exhausted with one operation.
